现有数字信号自动调制识别方法大多只适用于无记忆信号，如PSK、ASK、FSK信号等。将有记忆 信号(MSK信号)和无记忆信号一起考虑，提出了一种改进的数字信号自动识别方法。该方法采用信号的瞬时统 计量作为特征参数，采用多层神经网络作为分类器。计算机仿真表明：当噪声采用高斯白噪声，并且信噪比大于 l5 dB时，识别率高于96％ ；当信噪比不低于l0 dB时，识别率不低于90％。-Existing digital signal automatic modulation recognition methods are mostly applied only to memoryless signals, such as PSK, ASK, FSK signals. Will have a memory signal (MSK signal) and non-memory signal into consideration, an improved digital signal automatic identification method. This method is the use of the instantaneous signal statistics as a characteristic parameter, the use of multi-layer neural network as classifier. Computer simulation shows that: When the noise using Gaussian white noise, and signal to noise ratio greater than l5 dB, the recognition rate is higher than 96 when the signal to noise ratio not less than l0 dB, the recognition rate of not less than 90.

天线是由韦伯斯特的字典定义作为"通常是金属设备 （比如杆或线) 发射或接收无线电波。"IEEE 标准定义的 天线 （IEEE Std 145 – 1983） ∗ 的术语定义的天线作为"一种手段发射或接收无线电波"。换句话说，天线是过渡自由空间与引导的设备，如图 1.1 所示的结构。指导设备或线路可能采取同轴线或空心管的形式 （导），它用来运输从发射的电磁能量源到天线，或从到接收器天线。在前一种情况，我们有发射天线和后者的接收天线。
